BRAKE-CLUTCH.

Patented Feb. 20, 1912. Serial No. 649,021.

To all whom it may concern.-

Be it known that I, LUTHER T. TURNER, a citizen of the United States,residing at Artesia, in the county of Eddy and State of New Mexico, haveinvented new and useful Improvements in Brake-Clutches, of which thefollowing is a specification.

An object of the invention is to provide a clutch, particularly adaptedfor use in connection with elevators for applying a brake on the cableof the elevator to stop the elevator car.

My device is particularly adaptable for use in connection with elevatorsin which the operating cable passes through the car and in which theoperator can by a slight movement, operate the clutch to grip the cableand stop the car.

For the purpose mentioned, use is'made of a tubular casing adapted to bemounted within the car and through which the cable is passed, brakeshoes mounted adjacent the lower end of the said casing and adapted togrip the cable and means within the car for operating the said brakeshoes.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which Figure 1 is a frontelevation of the device, a cable being shown passed through the casing.Fig. 2 is a side elevation. Fig. 3 is a vertical longitudinal sectionalView taken on the line 3-3 in Fig. 1. Fig. i is a top plan view.

eferring more particularly to the views, I provide a tubular casing 10which is adapted to be mounted within an elevator car, the said casinghaving the operating cable passed therethrough with the lower end of thecasing extended beneath the floor of the elevator car. A bracket 11 issecured to the car adjacent the lower end of the casing 10 and mountedto swing on the bracket 11 are a plurality of brake levers 12 providedwith brake shoes 13. Pivotally connected to the brake levers 12 areoperating arms 14. pivotally connected to a sliding member 15 mounted toencircle the casing 10 and slidable thereon. Rigidly secured to theslid-.

ing member 15 are forked bearings 16 having pivotally mounted therein aplurality of forked rods 17 pivotally connected to an operating lever18, mounted to partially encircle the casing 10 and mounted to swing ona projection 19 of the casing 10.

The brake shoes 13 are mounted beneath the lower end of the casing 10and as the operating cable is extended through the casing, when it isdesired to stop the car the operating lever 18 is pressed downwardly,thus moving the brake shoes 13 into gripping engagement with the cable.To release the brake shoes 13 from gripping engagement with the cable,the operating lever 18 is moved upwardly, thus disengaging the brakeshoes from the cable through the medium of the brake levers 12, the armslet and the rods 17 connected to the sliding member 15 and the operatinglever 18.

If desirable suitable rollers can be mounted on the sliding member 15,the said rollers being pivotally connected to the arms 14 and adapted tooperate over the outer surface of the tubular casing 10. It will beunderstood that although for the purpose of describing my device I haveshown a particular form thereof, the scope of the invention is definedin the appended claim.

Having thus fully described the invention, what I claim as new, is

In a device of the class described, a tubular casing, brake shoesmounted adjacent the lower end of the said casing, brake leversconnected with the said brake shoes for operating the same, a slidingmember mounted to encircle the said casing and slidable thereon, armsconnecting the said brake levers with the said sliding member, bearingssecured to the said sliding member, an operating lever and rodsconnecting the said op erating lever with the said bearings foractuating the said brake shoes when the said operating lever isactuated.

In testimony whereof I affix my signature in presence of two witnesses.
